So, you're looking at making a deck that's essentially like International Standard playing cards, but using twice the number of suits and a few extra ranks. It's been done, and many times before, in fact. On the whole, they tend to be more of a curiosity than something that catches mainstream attention. The further you stray from the familiar, the tougher it can be to find an audience for it. But there is a caveat to this...
Look at games like Uno - it's played far and wide, it's popular (or at least as popular as any card game using non-standard cards is), but it's sort of a stripped-down version of standard playing cards, in a way. There's no court cards, though there are "special" cards - and the special cards have very simple instructions for their use. There's a shortened rank structure rather than expanded. And while there are more colors, there are also no suits.
If you're making specialized cards, make a specialized game to go with them. Keep the game strategically simple, fun, easy to play. Do try to sell them as a replacement for standard playing cards - sell them as a standalone, wholly-unique game all on its own. The largest Kickstarter project to date was a fairly simple, standalone card game with a big sense of humor - Exploding Kittens. The creators asked for $10,000. The ended up raising over $8 million. I'm not saying you'll automatically get those results, but I suspect that you'll do better making a standalone game rather than rejiggering standard playing cards into something new and unfamiliar.
