A moral/ethical question regarding my Rek-O-Kut Rondine

Hello.  I hope that you are well and enjoying life in general.

I am putting together a Rondine turntable with a tone arm that is too long to be mounted in the existing hole and too short to be mounted offboard -- on the tonearm side anyway but it fits nicely along the top.

But mounting the tonearm across the top is kind of wrong.  I could cut off the corner of the Rondine but that would really really be wrong.

Or is it?  Would it really be a bad thing to cut the Rek-O-Kut's deck?  I mean, that's kinda permanent but it would put the tonearm where it's supposed to be, and maybe that's a more ethical thing to do.

So tell me.  Has anyone done this?  Has it ruined your karma or condemned you to hell?  Did you hurt the turntable or did it really not mind at all?
