Red devil spiders from the Canary Islands have a genome half the size of mainland counterparts - Pisarenco, @jrozasub.bsky.social et al. show how purifying selection against slightly deleterious DNA and TE insertions is the primary mechanism.

I think a combination of long read nanopore at low depth - maybe washing flow cells to load 4 genomes on one and short read (fragmented with gtubes to 8-10kb) might make it cheapest.
