Cornwall 1 crossovers

I have a pair of Cornwall’s I’s purchased 10 years ago from the original owner.  They sound great. They had the original caps which I replaced thru Crites.  I also replaced the stock tweeters with Crites CT 125.  While I’m happy, and not obsessed with improvements, I do wonder about the stock crossover’s.  Any advice on upgrades that would make an audible difference?  Or leave well enough alone?

Thanks for any insights
