I'm minimum is simply irrelevant partner will assume you are anyway when he doubles them, the only relevant thing is you are NOT sub-minimum in which case you should bid something to warn partner.
I don't have clubs is not very relevant either. Opponents will bid, West is saying "I don't have any preference, you pick a suit. East will do so. If it turns out east DID have a penalty double after all and passes, a TD should have a look. And you're not even down yet, I've made 1♣ redoubled with an overtrick in a 3-2 fit after such a sequence (second level imps competition in the Netherlands), it happens and nothing they could do about it.
Now of course if you want to be able to always accurately get +90, +120 or +400 then 1NT to show a minimum if fine, just realize it comes at the expense of letting the opponents of the hook and NOT getting the juicy +200, +500, +800 in these occasions. If both partners agree to such an approach, sure why not, it's not mandatory to get good results as often as you can.
