Having a dangerous propensity to experiment I sympathise, but I still assign 3
♣/
♦ to 5-5 minors, arguably one too many.
Do you have neither available?
Transfers to minors occasionally work wonders and rarely do damage if both remember the agreements.
I personally play 4-way transfers, but the case for the 2-way (3-way?) 2
♠ bid is that on the normal auctions 1NT-2NT(inv); 3NT, or its modern sibling 1NT-2
♣; 2X-2NT(inv, doesn't necessarily promise a major); 3NT the defenders know far too much about the combined assets of the hands. 1NT-2
♠(inv without a major, or a long minor suit, or some very strong hands); 3
♣(max)-3NT can be bid both on strength but also on questionable hands with a minor suit that might well produce tricks, and it is not clear whether to go for a passive or an active lead. It's not so much the long minor suit hands that are the problem, but the invitational raises.
One interesting alternative is to ignore invitational hands entirely, simply jumping to game or passing. This frees up the sequence used for invitational raises for some slammish hands without costing much in practice.

I agree that East's double should be T/O.
