FSA Carbon Pro modular spider?

I have an older FSA Carbon Pro crank with a 110bcd spider and a Isis interface. I have seen that the newer modular cranks and mine both use the same lockring removal tool.

​​​​​​I know that the crank I have was available in both 110 and 130 bcd,both having removable spiders. I have a plethora of single speed non ramped or pinned 130bcd chainrings but only the 50/34 110bcd chainrings that came on the crank. I have had poor luck finding a 130bcd spider to replace my 110bcd spider

My question is if I can't find a spider can I use a newer modular 1x chainring to replace the spider? If so what is compatible?.

​​​​for reference,the bike is a Single speed but I might convert to a 1x10 in the future. Pics of bike and crank.

I understand that a modular chainring will affect my chainline but I'm using an 11 speed wheelset so the rear cog can be moved inward/outward to correct it,but if I run 1x10 in the future then it might be a problem.

Basically,can I use a new 1x ring on my old crank and what's the chainring I'll needs interface?

Edit: I also have a RaceFace Cadence crank that is 130bcd on a different bike,is there any advantage to using the RaceFace over the FSA other than chainrings? The FSA is a bit lighter and has a little bling compared to the RaceFace so I think it's better suited to the Lemonds neo-retro build.

I think your spider question would be best addressed by FSA. I would not be too concerned about the chainline on a 1 by whatever; it is only ideal on one rear cog anyway.
