I do the opposite and shoot on a snooker table. I don't play snooker, just make pool shots on the snooker equipment. The demands of snooker equipment force you to iron out any imperfections in your delivery in a hurry. Not only that, but it is really good for improving your focus as, for me anyway, it is all just different enough to feel like new. The table is higher up, the balls are smaller, everything looks a bit different, so it forces me to focus, aim, make sure of my aim when down, maybe even exaggerate the pause in my backswing to really get my eye in. With pool, you get away with so much it is easy for lazy habits to creep into your game before you even start seeing them show up as misses.
"Struggling" and "slump" are relative terms tho. For a guy like me, snooker is a better option because I don't ever lose confidence in my technique or what I am trying to do the way I don't lose confidence in my chef knife. I just understand both still need sharpening once in a while. A string of misses doesn't have me frantically searching for solutions and questioning my technique (as it used to). If you aren't through that stage of your pool development yet, perhaps playing on easier equipment may work better than more difficult equipment.
Like a 3point shooter that's gone cold, sometimes it is good to get closer to the basket, make some easy shots, and get used to that feeling of expecting a shot to go in every time. Rather than playing games on a 7 footer, you might be better served by not playing at all and work on some progression drills for shots that recently gave you trouble. You start with short easy shots you can be confident you are seeing right and just let that stroke out a bit. Then keep incrementally increasing distance of CB to OB or OB to pocket and do your best to maintain that same confident stroke as the shots become tougher.
