Martin,
the dual pump approach is very interesting. What is the smallest amount of epoxy you can get from this?
Our approach with epoxy is different. We got pumps with the kit but never used them. We simple pour and weigh on a digital kitchen balance. Worked great so far, even with small amounts of a few grams only. We never had issues such as epoxy not curing.
About fillet sanding. We let the fillets cure for 2-3 hours, use the alcohol-finger-trick to smooth the fillet and then immediately glass over the still 'wet' fillet. For sanding the glassed fillet, I have a hand-sanding-block made of cork which works surprisingly easy. In case of longer (meters!) fillets like the ones in the cockpit or footwell, using our smaller sander with a flexible disk and some caution works very well too.
