Perhaps, but

The the scale length is on the long side for the 5th tuning playing.

I'm not sure 5ths works across 6 strings, at least not on a guitar. I've tried but I've always got horrible "extra" sounds from the other strings. I think it is moving the other way (and with the opposite effect) from say moving a guitar towards more open tunings where other/sympathetic strings may add to the "full" sound.
