there is no gain in that as it is basically a tex catcode regime with a 
few differences; if you look in m-mkxl it's more some other things that 
can clash (they use some \meaning stuff and we need to temporary disable 
overload mode and disable some neat new features and such)

make sure to get rid of the t-tikz modules
