I can't see it happening, I'm afraid.
1) They're too closely related at the time, so they will at least require Papal dispensation.
2) William Clito is too young to marry when Matilda has her first marriage in 1114, so he'll have to be wait until 1125. At that point, Clito is not just a rebellious Norman, he's a defeated rebellious Norman.
3) William Clito is not popular with the Anglo-Norman barons, who are quite fond of their independence from the French crown, which William poses a threat to, having pretty much been Louis VI's pet since 1190 (this was a problem they Anglo-Norman barons had with Matilda's OTL husband Geoffrey).
Henry I gains little from having his daughter marry Matilda. I suppose it perhaps means he can name William as his successor, rather than Matilda, and thus secure his line upon the throne. But what he (and Matilda) gained from the marriage to Geoffrey d'Anjou is making an ally out of a former Norman enemy, Anjou's massive tracts of land, and their armies.
If it were to happen: the Anglo-Norman barons would invite Theobald or Stephen of Blois to take the throne. Without the land and arms of Anjou behind them, Theobald or Stephen win, establishing the House of Blois on the throne of England.
