Making an IPA starter with stout wort?

[Torrefaction]

Hi all,

First off, what a fantastic resource. So glad to have found this forum.

I'm a total noob about to start my second all grain batch (an IPA, which will also be my second batch of brew ever) with my first one already fermenting (a stout). My question is: can I use some of my leftover sweet wort (unboiled runnings) from my stout to make a yeast starter for my IPA? I collected about 1.5 pints from batch one, and I've had it in the fridge for about 4 days, covered. It tastes great - nice n' sweet! - and looks/smells a whole lot better than the DME I mixed up for my last starter. I understand the fact that I'll have to dilute it to bring it within 1.030-1.040 - just wondering if this is a good idea in the first place, or why it may be a very bad one!
Thanks!

should not be an issue. especially if you take care to decant the starter
