engine swap in 95 impreza

I've considered doing a frankenmotor or a EJ20 turbo swap in the impreza now that i've got it a m/t vehicle. I'm considering this

Only issues it seems to have is i'll have to find a way to convert cable to hydraulic clutch. It also seems they have the same trans so i could possibly use the cable clutch/trans and just bolt up the engine and keep the tranny as a spare. It has an ecm and harness but looks like the ecm harness was cut so i'd have to modify my existing harness to make it work. I'd also have to get a 97+ GS hood with scoops for intercooler.

I've also considered a complete overhaul

This would give me big brake upgrade, RHD, EJ20T with legit JDM body panels and everything.
