Default IAG shortblock swap - Pro shop or DIY?

Hello all,
I have a FBO 2018 base WRX, 6k gentle miles, Brentuned for e60. It is stupid fun already and I have no idea why I'm even thinking about this but here goes...

Remove the looming dark cloud that is the stock internals.
Max HP/TQ on stock turbo.
Reliability (I know..)
Daily driver, occasional spirited pulls, mountain runs.

Can a meticulous and technical person with a garage, a tool budget, and no motor building experience swap in an IAG stage 2 short block using just the WRX service manual or other guides?
What documentation do most people use?

What are the bare minimum supporting parts, accessories, and materials? I'm guessing beefier clutch while I'm in there.

What minimum head work is required vs. the "while were in there" tweaks? Where is best to source head work?

I know I'm asking a lot and this probably could be about 7 threads, but I dont need a deep dive yet, just the basics. Thanks in advance!
