Are there any more VX Ace Mack tilesets?

So I got the Mack tileset for VX Ace, and it has some awesome stuff, but unfortunately as it's only one tileset it also lacks a lot of things, such as castle parts.

I was wondering if there's any more Mack tilesets out there. And if not, is it generally considered acceptable to use Mack's tileset in conjunction with the RTP tilesets?

You can totally use tilesets together, just make sure to credit everyone.

Sharm is right legally --- if you give proper credit to everyone, and have the legal rights to do so, etc, you can use any tileset you want.

The only thing you need to watch for is:  Do the sprites look silly going from one tileset to the other?

I don't mean outfits, I mean some sprites have different shading, color palette and such which can look extremely goofy when used on a completely different style of tileset.  Mack and VX ACE's chibi style sprites, for examine, don't work well together.

I'm using the Mack sized sprites, but I was just wondering if it's visually acceptable to use those Mack tiles with RTP. Like, are there people who've done that in the past, and is it generally encouraged or discouraged, etc.
