It is not desirable to place a deactivating group such as SO3H, NO2, CN etc on an already deficient carbon atom..i.e positive charge as you depicted in your diagram.

If the group is electron donating.....resonance effects and in the case of an alkyl group such as methyl...hyperconjugative effects help to stabilize our cationic intermediate,,,,,also known as the arenium ion.

I like what I see !!!!

Hope this helps.
