I think that playing against good opponents the auction is just as likely to proceed 1♦ - 1♠ - 5♦ than if you bid 4♠ directly.
I think I'd start out with a double and then bid spades at my next opportunity (unless partner bids clubs). Partner only needs 1 of 3 cards (with some clubs) to make slam very very favorable.
The first is not necessarily true. Certainly a pure diamond preempt will bid 5
♦ directly, but I actually feel more comfortable with the auction 1
♦-1
♠-5
♦-P-P-5
♠ than with bidding 4
♠ directly. There are many hands though which are not "pure diamond preempts" and would start with a negative double, 2
♥ bid, or 2
♠ "strong diamond raise" over a 1
♠ overcall but would bid 5
♦ over 4
♠. Also the hands where opener will rebid 5
♦ will typically take some other action in order to establish a force and/or show long diamonds (i.e. 1
♦-1
♠-P-P-2
♠ or even 1
♦-1
♠-X-P-3
♦); I'm not sure I've
ever seen a good player open 1
♦ and then jump to 5
♦ at second turn when the auction is only at the one or two level.
As for doubling, I'd be afraid partner bids hearts, or that partner tries to penalize thinking we have more defense than we've shown. I prefer to limit my "power doubles" to hands where I have a serious fear that the hand will pass out if I make a simple overcall, which seems unlikely here given the distribution (and lack of hcp values).
