Can I use a 4L80 trans?

I’m beginning to consider changing out my TH350 trans for one of the Following.
1.700R4
2. 4L60
3.4L80
What are the Pros/Cons of each, in regards to Electronic Wiring and reworking, Trans Tunnel clearance or modifications required, Crossmember mods, and Driveshaft requirements.
I’m considering the changeover to one of these Transmissions, for the advantages of OD on the Highways.
Any advice is welcomed
