I wouldn't recommend that.

First of all, this would increase parse time on a daily basis.

Second, in any scenario where many random numbers are needed and their
order doesn't matter (such as when randomly placing many objects), this
would be virtually useless as it would only ditch the first few random
numbers and replace them with what would then be the last few random
numbers.

Third, two sequences even from neighboring seeds should diverge
sufficiently after a few couple of values (maybe a dozen), so throwing
away a small fixed count of random numbers should suffice.

That is, unless the seeds only differ in the fractional part (e.g. 471.1
vs. 471.2), in which case the sequences will be completely identical.
But the same goes for the approach you're presenting.
