So I went through these and I'll let you know which ones we can and can't test (also the reasons why).
Peach - No, only has one spawn which is a clusterfuck.
Dark Tower - Possibly (leaning towards no), it's a CTF map. Unless @Moosty @Rejects @metalslug53 @kbraszzz want to change the server so it's trade and rotation, it will be a no.
Aquatic Ruins - Same as Dark Tower, it's a koth map.
CTR N.Gin Labs - Possibly, it's a mario kart map. Same reason as Dark Tower.
Metal Gear Solid - No, it's a generic arena map.
Nuketown - Possibly, appears to be koth (you can see the control point on the screenshot).
Pac-Man - No, it's a generic CP map.
Whomp Fortress - Possibly, looks pretty small. It's VSH (aka koth), so same reason as Dark Tower
Portal - Yes, it's a trade map. Might be interesting.
Kokiri Forest - Possibly, it's a payload map. Same reason as Dark Tower.
Lavender Town - No, it's a pointless map that I already tested with Rhodo. It has no buildings to go in, not to mention the CP. It's also horribly optimized.
TL;DR-
Yes:
Portal
Maybe (per agreement of @Moosty @Rejects @metalslug53 @kbraszzz ):
Dark Tower
Aquatic Ruins
CTR N.Gin
Nuketown
Whomp
Kokiri
No:
Metal Gear
Pac-Man
Lavender Town
Peach
