If this is the case then the Krath warships and Republic technology go down in flames. Bassilisks are quite dangerous, more firepower than any starfighters of their time, able to take down ships much, much larger than themselves, and they are war mechs, not just vehicles. Semi-sentient, able to fight in melee range and bombard from a distance.
I don't really like seige scenarios, but are we looking at EK holding up at Y4? If so I call shenanigans. Mandalorians are known to sling-shot nukes, and they could bombard Y4 into a smoldering crater.
