Not at all. It just sounds a slightly more relaxed/warm/tolerant-to-bad-recordings. And it has a bit more gain.

could be just another of my usual crazy ideas

but considering that size may not be the main cost of a board like this....would it be possible, and make sense to also put Juma's multiplier on it as well

or would it end in a much more expencive size category

because a bigger board might not be a lot more expencive
I thought if it could be made 'breakable', or to be hacked off, by sawing, or whatever

but may result in looking 'less nice'
maybe not so simple as I first imagined

or, a breakable board could also be a more cost effective way to get 4 of your regs, etc
if some only want 2, you can break them yourself before shipping
but I don't know the prices
