1994 Excel, has anyone tried to install 1998 Accent engine

My lady friend has a good 1994 Excel and not much money with a bad (seized-
up) motor and I have a 1998 and 1999 Accent that have been totaled in the
rear... The engines and engine cradles are good and still run (57K miles).
Is there any way (within reason) to install either of them into the Excell?

 

Recently had to take my XG in to get the radio replaced because it kept
turning itself on. I don't believe I'm the only one that's experienced that
problem. However, I had to take it in the first time for the dealer to check
out the circuits to make sure it wasn't just a wiring problem, or so I was
told. No, it WAS the radio. The dealer ordered one & I went back a couple of
weeks later to get the 'new' one installed. Dealer looked after me right
away BUT a 1/2 hour later I realized that the #%%$@*& CD player didn't work.
Now here's the catch, it takes me 5 hours round trip to go to the closest
dealer!!!! So far I've got 10 hours of drive time into getting what I think
should be straight forward warrant work done. The dealer is annoyed too that
they were given a defective radio but that's nothing compared to my 15 hours
driving into getting the &**% thing fixed by the time the next one is
installed.
On top of this I've got shimmy in the front end when I hit the brakes when
they are hot. I've told the dealer I want them fixed under warranty & if
they don't do it that way I can & will do it myself but then my next new car
won't be a Hyundai. That would be too bad b/c otherwise the vehicle has been
very acceptable.
