As has been explained, double is penalty, 4NT is this minor suit shape, 5C would suggest 6–5 minors (or, weirdly I suppose, something like 0=4=5=5 — in any case a one-card difference).
I don't hate 4S. The real problem with it is that it could miss a slam. If partner has as little as AKJTxx xx xx xxx slam isn't awful, and if you add either the spade queen or the club king it's pretty good. In other words, if partner has his 2S bid you'll often make a slam.
I bid 4NT, then 5S over either minor (or over 5H if opps bid it — yes, I'm turning down 5HX, but I think any time we are making six tricks against 5H I want at least to take the shot at slam). This should describe my hand reasonably well, and presumably partner will pass if he's ashamed of his 2S bid (and we'll still probably make it) and bid on with ace-king-king or better.
