I guess I am always surprised that home brewers view the very minimum size for any experimental batch as 5 -6 gallons. Would the beer gods strike you down if you experimented with a single gallon? The wine gods wouldn't. And so if the final result was undrinkable swill at the most you would have to pour down the drain a gallon. Much easier to toss a gallon out than swallow 5 gallons of pigswill. But it is unlikely to be awful. The bigger problem is that you think it MIGHT BE and still you decided to make enough for an army.
The thing about SP is that the slurry WILL modify the color and the flavor but only a little (of course, if the slurry is 50% of the total must then it could have a LARGE impact. My money is on the idea that after it clears the color will be very faint , but as for the hops... They might provide a somewhat intense vegetative flavor. Even after dry hopping you want to remove the hops from the alcohol within about two weeks at most.
And here's the other thing about SP. There is really no formal "original" flavor. Whatever slurry anyone used will flavor and color the SP. You used slurry from strawberry wine, that will be very different from the lees from grape wines, and those will be very different from a yeast cake from blueberry wine. Me? I make SP using lab cultured yeast. Different yeasts will have noticeable impact on the final result but noticeable does not necessarily imply good or bad. If I use the same yeast, then the batches will be very similar.
