Morph targets with dynamic materials

Hi everyone,
I’ve a question that couldn’t find any valuable information, hope someone can help.

I’ve this character that has a set of Morph Targets which I can control the deformation with some sliders for example.
The thing is that each Morph Target has its own texture and normal. For example, one texture for a Neutral pose, another texture for a Disgusted pose and so on. In which details on the skin change.

I was wondering, is there any straight-forward way that I could interpolate between these different textures in the same way I can between the Morph Targets? How can I assign different textures/materials to different Morph Target poses?

I already tried Lerping and modifying the lerp parameter via blueprint but it doesn’t work so well and also seems good for only two different expressions but I would have several, each one with its own base texture and normal.
Very close to the “Morpher” material in 3ds Max for example.

Is it possible?

I’m attaching a screenshot illustrating the issue.

Thank you!

Did you ever find a solution to this? would love to know
Thanks
