Did you see that there are MTL pinholes in the dead rabbit SQ? Turns it into a fairly tight surprisingly adept MTL atty for still being 22mm. I only played around with the air after my coil was in (and it was a big fancy clapton) and it worked pretty good. I would imagine building up close to the pinholes (and an appropriately sized coil) would take it to the next level for MTL.
