Purple to Red Iso Converter

So after toying with the new Supports feature and having leveled one of my supports to level 64 out of 200 (Rank 4 Hydra Henchmen), I've realized that Supports take a lot of red iso to level at higher levels. For instance, to get to rank 65, I would need 1169 red iso.
This is where my suggestion comes in - an iso converter.
I propose, in the future, that we be able to convert any purple iso we have into red iso. I think a good conversion rate would be 10 purple iso per 1 red iso. It allows red iso to still be limited while giving people with excessive iso stashes (like my 3 million+ stash currently) an avenue to spend their resources that would otherwise sit unused.
10:1 doesn't have to be the ratio enacted if this idea were to be used, but hopefully something reasonable along those lines would be what would happen. If, for instance, the ration were something like 100:1, then it would feel more like an insult than an avenue in which to help players use the resources they've earned in meaningful ways, emphasis on meaningful.

Edit - And if they added a purple to red converter, I'd play so I could get more purple to convert to red, haha.
I envision aamad scientist contraption that takes up a character slot. Players pay iso 8 to be converted and then face a torrent of ever increasing foes that flood out of a portal caused by the conversion process. You get two characters and a machine with passives, I figure a consume protect to restore it's health each turn to cut down on turtle for the win strategy. I see it as a play til you drop mechanic with improving conversion rating for each wave.
Would get players playing, the until you drop encourages health packs and roster rotation, and players get to farm for that riso. Could even throw in some rewards for reaching wave x.
