Lamy ink in Kaweco liliput

Has anyone tried Lamy or Pelican 4001 in a Kaweco liliput (or sport as I assume the feeds are the same)? I know that Lamy cartridges are proprietary, that's not where I'm heading with this. I did manage to find a Kaweco folding converter that will fit my liliput while I was in Europe. Perhaps this is better phrased as:

Ignoring the practical limitations of refilling the Liliput, what inks work well?

I assume that Kaweco ink bottles are the trivial solution here, but Im new to this and don't want too many bottles of ink laying around.

I did my fair share of independent research before posing and couldn't find a good list of what inks work well. What are your experiences?
