Canadian Liberal Democratic Party in the '70s

Wikipedia said:
Trudeau was known to be a friend of Fidel Castro and Cuba. A mobster said that in 1974 he was hired by New York State mafia members to kill Trudeau, hoping to bait Castro up to a funeral, where they would kill him. The plan was apparently later rejected.

I think it would be more interesting if this happened in 1972 or so, and Trudeau lived. So, because of that...

1972 - Trudeau survives his assassination and popular sympathy leads to a majority government
1976 - Robert Stanfield wins a minority government, supported by Social Credit but not the NDP

How plausible would it be for Trudeau to try to merge the Liberals and NDP in opposition to make the Liberal Democratic Party? The only reason he switched from the NDP to the Liberals was for power purposes after all. I think I remember reading from our Canadians that the only Liberal PM after Trudeau who could've done such a thing without totally isolating Centrist Liberals was Chretien. If Trudeau tried this, would he succeed? Even if there was a chance he would alienate Centrist Liberals to the PCs, I doubt that would stop him from trying if he was dead set on it.
 
I have repeatedly mentioned in Chat that merging a liberal and socialist party, even if the distinction was highly blurred during the Trudeau era, is ASB. Neither party's base will stand for it and the centrist Liberals will not let it happen. Trudeau never favoured the idea and would not push it to the point that a caucus coup would become necessary. There was no reason to do that, and the idea was never floated in either party.

Stanfield: if Trudeau gets a majority he's out, he never had full command of the caucus anyways (most famously with the Official Languages Act, where Dief and renegade Blues voted against). Next Tory leader is probably Claude Wagner.
 
A somewhat related question: Anyway for the PC never to break (i.e. no Reform Party and BQ).

Meech passes if the provincial legislatures ratify it immediately (by mid-1989), no BQ, no Reform. PQ is dealt a blow but a demoralized PLQ loses power in 1994 regardless. Mulroney retires as planned (source: his memoirs) in the fall of 1991, succeeded by any of the Cabinet heavyweights: Wilson, MacDougall, Mazankowski are the most likely. If they're smart they'll pick Maz, an Albertan.
