Okay, to clear up a few issues...
I am playing a 5 string bass tuned B E A D G. The guitarist/vocalist is tuned D A D F# A D. He has it in his head that he wants to try Eb Bb Eb G Bb Eb. Let's not discuss the merits of retuning or not retuning for the moment - he and I are good friends and have played literally hundreds of gigs together since 2017 - or 100th gig of this year will occur in late October. The dude is a good guy and a really good entertainer. We have a lot of fun and make a good deal of money. I'm willing to try it on a "let's see what happens" basis.
His point is this - if he finds that he likes playing with his guitar tuned up a semitone, it will be easier for me to just tune my bass up a semitone so as not to have to relearn all of the songs a semitone up. You need to keep in mind that at this point we have a rep list of over 1200 tunes. They are in just about any key you could think of, though none D minor because it makes people weep instantly when you play it.
On one hand, I have no problem playing the songs in regular tuning up a semitone. Most of what we play is not rocket science, and I've never depended a lot on open strings. On the other hand... 1200+ tunes is 1200+ tunes, so saving some effort might be worthwhile. Plus, it freaks him out that I will just play the songs in a new key. I'm not sure why. And as @Dirk Diggler mentioned, communication may become an issue.
To answer any questions about keys... don't overthink the issue here, I could care less which keys we play tunes in. I don't think my guitar player can think that way, but I am ready to play whatever song in whatever key. Makes very little difference to me. My only real questions - and the reason I posted - lie in the mechanical effects on the bass... neck bowing, string tension, intonation, etc.
