4cyl to 6 swap? a 4.3 GM? or other more efficient

My quest continues...
So I stopped by a mechanic the other day and he said if I bought a four cylinder jeep and wanted to swap out a six later in its worn out life it would not be a good idea because the four is a GM. No mechanic in their right mind would do it citing wiring harness' etc. So I was wondering if you could switch the four cylinder GM for a six cylinder GM (4.3 maybe . SO...I know you guys have some ideas on this stuff. I am sure I am not the first one to think of it. Well thanks for the input.

The 2.8 V-6 is a Chevy.... the 2.5 I-4 is an AMC. Has been for about 30 years. The wiring might be a prob still however due to the TJ being basically a "new" platform, the computer might not like the change. Good Luck!
