Trade dilemma

[Hollywoodvillain]

I am looking to change up a watch or two and would like some opinions to see if im going at this with my head on straight .

I currently have only 2watches

1. 16600 SD4K
2. 16760 GMT "fat lady"

Im thinking of parting with the 1991 N serial 16600 Seadweller with nice creamy patina on hands plot Lume and bezel pearl , boxes ,tags,book,anchor, NO warranty paper.

I was thinking I would get an EXP 1 and a 14060 2 liner to replace the sea dweller !

Then I stumbled onto a possible trade for a milgauss Blk dial green crystal full kit and a TAG aquaracer both for my dweller !
I would sell the aquaracer right away hopefully for about $1000 and start looking for a 14060 2 liner which I would obviously have to put some money into n for !

I guess I'm asking if a pretty clean Blk dial green crystal full kit milgauss and 1000 is a good deal for my very clean 1991. N serial Seadweller ! And if the milgauss will wear similar to the 39mm explorer 1 ?
