If I use a Chthonian Exchanger on a VM 15x/15x/15x gas, will it become a VL 28x/28x?
It does not work like that. it would be probably 2x MR. 15x MR is a value of 27 (see following link:
http://galaxylegion.com/wiki/index.php/Planets) (down page under resource availability chart) half of 27 is 13.5 which if rounded up would make it 2x MR(value of 14 on the chart) I'm pretty sure it caps at 15x MR. So if you had a research planet that was 20XMR and converted it, it would still only be 2x MR
