I recon not as seeing,nessie was his to imprint on.she doesn't exsist so no imprinting.But it does make sense why he was so atracted to bella,because she cared part of nessie in her already.
For starters reckon? Where did 你 learn english?Also no Jacob would not of imprinted on anyone else, it's a kind of one time thing so once it's gone it's gone.
你 know what would have been funny, if bella "had" choosen jacob, they would have had children. and because jacobs attracted to bellas egg (renesmee in the "before" books) then his female child would be the subject of imprintinasation lol. i know thats discusting but as true as fiction gets.
I think he would have just been with Bella and never really "officially" imprinted on anyone. There wouldn't have been a Renesmee because Edward and Bella wouldn't have had her...
Remember..they dont have any control on the whole imprinting thing...look at Sam and Emily ...he was in 爱情 with Leah but then the 分钟 he saw Emily.."imprinted"...so maybe Jacob would have imprinted on someone else...maybe he wouldnt have...we may never know...and the good thing is that we dont have too...
