I don't think so.
Krishna told Duryodhan after the war that his refusal to give Pandavas their share led to the war. The implication is that if Duryodhan had agreed to Krishna's proposal then there would have been no war. There is no need to unnecessarily give complicated explanations of Krishna's motive.
Krishna’s admonition to Duryadhana
Duryodhana began to afflict Vasudeva with keen and bitter words, "O
son of Kansa's slave, thou hast, it seems, no shame, for hast thou
forgotten that I have been struck down most unfairly, judged by the
rules that prevail in encounters with the mace? It was thou who
unfairly caused this act by reminding Bhima with a hint about the
breaking of my thighs! Dost thou think I did not mark it when Arjuna
(acting under thy advice) hinted it to Bhima? Having caused thousands
of kings, who always fought fairly, to be slain through diverse kinds
of unfair means, feelest thou no shame or no abhorrence for those
acts? Day after day having caused a great carnage of heroic warriors,
thou causedst the grandsire to be slain by placing Shikhandi to the
fore! Having again caused an elephant of the name of Ashvatthama to be
slain, O thou of wicked understanding, thou causedst the preceptor to
lay aside his weapons. Thinkest thou that this is not known to me!
While again that valiant hero was about to be slain this cruel
Dhrishtadyumna, thou didst not dissuade the latter! The dart that had
been begged (of Shakra as a boon) by Karna for the slaughter of Arjuna
was baffled by thee through Ghatotkacha! Who is there that is more
sinful than thou? Similarly, the mighty Bhurishrava, with one of his
arms lopped off and while observant of the Praya vow, was caused to be
slain by thee through the agency of the high-souled Satyaki. Karna had
done a great feat for vanquishing Partha. Thou, however, causedst
Aswasena, the son of that prince of snakes (Takshaka), to be baffled
in achieving his purpose! When again the wheel of Karna's car sank in
mire and Karna was afflicted with calamity and almost vanquished on
that account, when, indeed, that foremost of men became anxious to
liberate his wheel, thou causedst that Karna to be then slain! If ye
had fought me and Karna and Bhishma and Drona by fair means, victory
then, without doubt, would never have been yours. By adopting the most
crooked and unrighteous of means thou hast caused many kings observant
of the duties of their order and ourselves also to be slain!'
"'Vasudeva said, "Thou, O son of Gandhari, hast been slain with thy
brothers, sons, kinsmen, friends, and followers, only in consequence
of the sinful path in which thou hast trod! Through thy evil acts
those two heroes, Bhishma and Drona, have been slain! Karna too hath
been slain for having imitated thy behaviour! Solicited by me, O fool,
thou didst not, from avarice, give the Pandavas their paternal share,
acting according to the counsels of Shakuni! Thou gavest poison to
Bhimasena! Thou hadst, also, O thou of wicked understanding,
endeavoured to burn all the Pandavas with their mother at the palace
of lac! On the occasion also of the gambling, thou hadst persecuted
the daughter of Yajnasena, while in her season, in the midst of the
assembly! Shameless as thou art, even then thou becamest worthy of
being slain! Thou hadst, through Subala's son well-versed in dice,
unfairly vanquished the virtuous Yudhishthira who was unskilled in
gambling! For that art thou slain! Through the sinful Jayadratha
again, Krishna was on another occasion persecuted when the Pandavas,
her lords, had gone out hunting towards the hermitage of Trinavindu!
Causing Abhimanyu, who was a child and alone, to be surrounded by
many, thou didst slay that hero. It is in consequence of that fault, O
sinful wretch, that thou art slain! All those unrighteous acts that
thou sayest have been perpetrated by us, have in reality been
perpetrated by thee in consequence of thy sinful nature! Thou didst
never listen to the counsels of Brihaspati and Usanas! Thou didst
never wait upon the old! Thou didst never hear beneficial words!
Enslaved by ungovernable covetousness and thirst of gain, thou didst
perpetrate many unrighteous acts! Bear now the consequences of those
acts of thine!"
