Same thing for the tuba and euphonium at the lower end if the euphonium range.
I would say "yes." Often in British brass bands, for example, lines are passed from one section to the next lower or higher section, and a very different tone upon handoff would lessen the effect. Think of the strings in orchestra. It can be tough to tell sometimes when they play in a connecting/overlapping range... Is that a violin or viola? Is it a cello or double bass?
