Hey Guys, name as many instrumental trios with just guitar, bass and drums you can think of

The reason for this is, that we're thinking about making an instrumental trio, but are not sure how that would sound, so we're collecting different ideas etc.

Hard to do. If someone is handling the melody who will handle the chords and rhythm? There are lots of trios but they all have singers or at least one of the members of the trio sings. Maybe you are onto something completely original. Good luck. (Look up Link Wray "Rumble" on YouTube)
