My view is that as long as the musicality is there, it does not matter, however if the player is not extending his/herself, then they are not really accepting the challenge of the original key.
Thanks for reading!
To answer your question: most of us just want you to sound amazing, no matter what key you're in. Anybody that judges you for it is a jerk.
However! You should try the Eccles in G. I've never heard of anyone playing it in A unless they were using solo strings (thus, they're still fingering in G). Is it possible you have mistakenly taken a solo tuning piano score? That would be written out in A minor, but would not be intended for the bassist to play from.
If you spend some time in the proper key, you may find G minor to be much easier. I would especially hate transposing those chords in the second movement into A.
