Hard to say. I've heard of people using eMMC readers from HardKernel with Pine64 eMMCs, but I'd be cautious of them being drop in replacements, as there are likely differences between them, like all other eMMCs.
Not currently, there's no way to select which you want to boot from. Currently the best solution (with a 50/50 chance) would be to flash a uboot to your SPI, put one OS on the eMMC and another on an NVMe, and use the eMMC switch to determine which boots.
In all honesty, if you want more space than you can get from the 128GB eMMC, you should just get an NVMe. The cost/space will be much better.
