Wyeast 1098 British Ale for a Midnight Beatdown Wheaten Porter?

I have an Oatmeal Stout in the primary, sitting on some 1098 British Ale yeast. Being delivered next week is the Midnight Beatdown Wheaten Porter and the Speckled Heifer.

Just wondering whether the 1098 yeast cake in my primary would be a good choice for the Porter, or should I use the 1056 American Ale that’s coming with the kits next week.

If I don’t reuse this yeast cake, I’ll brew the Speckled Heifer next and then use the 1056 yeast cake from that brew to do the Porter.
