And that would cost how much for a range of sizes to fit different size
lenses for occasional use?

You can use adapter rings, instead of buying new filters for each
different lens diameter. They are quite cheap.

Totally impractical for the range of lens sizes I use.

Why? You just buy the filters in the size of your largest lens and one
(step up) adapter for each (smaller) lens size you have. Adapters cost a
few Euro or dollar each.
So how many will I need to go from my 77mm down to my 49mm?

One. ;-)
I have one that came with my Zuiko 18mm f/3.5, but its not for sale.

one ring, although you might be better off with two if you have lenses
between those two sizes.

What a brilliant, high performance lens though. I use it on my Canon 5D
regularly as it still out-performs any equivalent.

In that case just do a google search for a 49-77mm step up ring.

I have 58mm filters from when I used the Sony F707. Otherwise, for all my
DSLR lenses that I might use filters on, I have step-up adapters to 77mm
and have 77mm lens caps on them. Simple. All I need is 77mm filters.

Actually I have just discovered that I cannot use a step up ring with my
DA15, simply will not fit so I have ordered the 49mm filters.
