I understand the desire to dump Qubit, since nzsquirrell seems pretty anti-ASIC, and there are now ASICs for Quark and Qubit (and X11) for the last year or so. There are certainly a lot of alternatives to just inserting another generic GPU-targeted algorithm, like Neoscrypt, especially since UIS already all GPU algos besides yescrypt (although some are probably FPGA-mineable as well). Could do something with some GPU/CPU parity, like cryptonight, or something like the BURST proof-of-capacity algo that uses HD space, or something completely different. I guess ultimately it's basically up to nzsquirrell, since he will probably be the one who implements any change...
