Perot support was stronger in states that went for Dole anyway. His supporters would not have swung enough states even if they all voted Dole (and a significant number said they would have voted Clinton or not voted):
"Reform Party nominee Ross Perot won approximately 8% of the popular vote. His vote total was less than half of his performance in 1992. The 1996 national exit poll showed that just as in 1992,[13] Reform Party nominee Ross Perot's supporters drew from Clinton and Dole equally.[14] In polls directed at Perot voters as to who would be a second choice, Clinton consistently held substantial leads.[15]" - wikipedia
EDIT: I cannot get more than 55 electoral votes that might have shifted, which still gives Clinton a victory.
ἡ δὲ κἀκ τριῶν τρυπημάτων ἐργαζομένη ἐνεκάλει τῇ φύσει, δυσφορουμένη, ὅτι δὴ μὴ καὶ τοὺς τιτθοὺς αὐτῇ εὐρύτερον ἢ νῦν εἰσι τρυπώη, ὅπως καὶ ἄλλην ἐνταῦθα μίξιν ἐπιτεχνᾶσθαι δυνατὴ εἴη. – Procopius
