Vanilla-Lavender Cream Ale

I would love to create a fun summer seasonal partial mash recipe that builds off a solid cream ale base and is infused with vanilla and lavender aromas. My plan for the lavender is to dry hop with it and the vanilla flavoring I will get by measuring out my priming sugar in advance and putting it aside in a container with a couple of split vanilla beans. I would love thoughts on both the base recipe and thoughts on how to keep the vanilla and lavender flavors from being overpowering. Here's the base:

4 lbs Light DME
2 lbs Two-Row Pale
1 lb Crystal 10L
6 oz Cara-Pils

0.5 oz Crystal pellet hops @ 60
1 oz Crystal pellet hops @ 30
1 Whirlfloc tablet @ 20
0.5 oz Crystal pellet hops @ 1

Yeast: White Labs WLP029 Kolsch yeast

Ferment 21 days at 62*
Pseudo-lager at 50 for 21 days
Add 1 oz dried Angustifolia lavender for 7 days
Prime with vanilla-infused sugar

I maybe be wrong but I think cream ales have adjuncts( corn/rice) in them. You may want to consider them. Good luck
