Why Not Retune The SBS's Upper Range?

[ted@xxxxxxxxxxxxxxxxxxxxx]

SBS Specialists,
	
	However naive it may seem (I'm no theory buff), I want to pose a 
question:

	Why not retune the upper range of the SBS, from the eighth hole up, in 
the same pattern as holes 2 through 8? 

Winslow's Schematic:

SBS in C:        |                                       |
                 |                                       |
     __1___2___3_|_4___5___6___7___8___9___10__11__12__13|_14_
DRAW | D | G | B | D | G | B | D | F | A | B | D | F | A | B |
     =========================================================
BLOW | C | E | G | C | E | G | C | E | G | C | E | G | C | E |
     ---------------------------------------------------------

	I know it would be unfamiliar (unlike a Marine Band tuning), but with 
so many alternate tunings already making memorization a necessity, why 
would this not be desirable? 
	I find I can run some melody lines from the "Marine Band" octave of 
the SBS into the lower or "bass" three holes/six notes more or less 
seamlessly. Why could I not do so at the top?
	When I first heard of the SBS, before I saw a schematic, I thought 
this might be the setup. When I found that it wasn't, I bought one anyway, 
and I find the SBS to be a really good addition to my harp arsenal. But 
still I wonder why this would not be a good modification. I guess any good 
harp mechanic could make the change. Right? If so, who?
