But there's also a lot more episodes where he's the same size as the other combiners in combined mode. I guess it depends on how you structure your collection. Will he stand next to Omega or the other Decepticon combiners? For me, since I'm not going into OS KO CW Devy and Titan Omega are too tall.
In the end either titan Omega and Devy are too large or all the other combiners are too small. And all the combiners mass shift anyway.

Yeah, it's a real mess thanks to the combiners mass-shifting to be larger than the sum of their parts.
CW Devastator in combined mode is Devastator at his combination-enabled mass-shifted size relative to normal-size TFs, at the price of the individual Constructicons being too big and the combined mode being out-of-scale with other combiners. The same generally applies to Predaking.
The other combiners have their individual members in-scale. They're thus not "step on everyone" size relative to normal-size TFs (note that I specify "normal-size TFs") like they are in the cartoon, although they're still of a respectable size due to not having midget limb-bots.
SIEGE Omega Supreme... He's as big as he should be next to normal-size TFs and mass-shifted Devastator, but too huge next to the standard CW-style combiners much like Devy is.
I will say that there
is a way to make the standard CW combiners look the mass-shifted size: Legion-class figures.
Regarding Piranacon/King Poseidon, since I'm assuming he probably came up in this discussion at some point... Piranacon never got to appear in the cartoon since in the US new episodes stopped in 1987, so it's hard to say how big he would have been in it. And the Marvel comics were even more hopeless than the cartoon so using them as a reference is iffy.
But we do have a more solid size reference on the King Poseidon end of things. In Masterforce he was in the same league as Super and God Ginrai size-wise, so being basically standard CW/PotP combiner size works out perfectly there.

Myself, I'd go with an
undersize KO of Devastator (easier on space, gives better-scaled individual 'Structies, and it just makes more sense to get a smaller Devy than huger versions of everyone else b/c the others outnumber Devy), an undersize KO of Omega Supreme (once one exists) to have one in show-scale with the combiners, and Titan-class Omega to have a version of him that scaled with normal-size TFs.
Also, there was something in your post not thought through

Luckily context makes it easy enough to figure out which OS is which.
