Sweater gauge and drape question

[untonuggan]

Question about sweater pattern alteration here:

I tend to pick patterns to pieces and combine the bits I like. I'm planning to knit caramel, which is a top-down cardigan that's got a lot of positive ease and is very drape-y, using some Malabrigo rastita and DK/light worsted handspun that's a mix of silk and wool.

My main question is, aside from me having to do math, is there a structural problem with me knitting in a looser gauge than the pattern calls for?

The pattern calls for 22 sts / 4 inches, and I just feel that because the yarn I have is very woolen and floofy, at that gauge it will be Too Stiff. Also, because chronic pain + hot flashes all the time, light weight cardigans are really more my style anyway.

I know for socks and things a looser gauge means you're more likely to get holes, and obviously it will be cooler (which I want). But other than that, is there any reason not to do it? I also know that because I'm using a lot of single ply, there will be Pilling Issues, but I can deal.

I knit a swatch with a gauge of 18 sts / 4 inches and I really like the way the fabric looks and drapes and feels so if there is not a problem other than those listed above, I will probably just go with that.

Thanks!

The thing I would worry about is that the fabric might sag under its own weight if it's knitted at too loose a gauge.Though with DK weight yarn that might not be too much of a problem.
