Does SoD on Beamdog client work with Tweaks Anthology without Modmerge?

What the title says.

I like to run with the BG1 weapon proficiency system throughout the trilogy.

I own everything including SoD on Steam, and everything *except* SoD on the Beamdog client. If I buy another copy of SoD for the Beamdog client, will I be able to run Tweaks Anthology without Modmerge?

Also, I really hate the black SoD interface. If I buy SoD on my Beamdog client, will I then be forced to play with the hideous black interface in BG1 instead of the pleasant blue?
