Here's what I did
Duplicated the background image then used a High Pass Live Filter on it. Set the duplicate background's blend mode to hard light then clipped the duplicate background to the text. Added a rectangle above everything with a gradient that has some noise in the colour.
Just a quick edit but I hope it gives you some room to expand on your design. You could also use Frequency separation (under the Filters menu), in step one, instead of the High Pass filter. I prefer the live filter approach for edibility though. Edit attached.
