I think I saw one (blast conv) couple of months ago but if you wanna make one a cheaper way (because bclub is expensive) buy the nonscale 1/144 and another HG impulse and take the back pack which work good (need lil work) you can make sure here

And no way 1/100 Destroy, and if there's a 1/144 there should be more Babi and Dinn (silver ones dont remember the name)
