You did say for one-off we should just use this board
(and buy another ;) - so the latter

If you stick to your guns- is there an adjustable version of the LDO so 
one just needs to swap resistors/move a strap?

I like the concept of 10F+LDO (would like to try it myself) but as you 
indicated if BOM is $10 and regulation is ~$3 or 30% of that and if your 
markup scales accordingly...

Success*
