I have to admit, your description reminded me of a toy (plastic model) that I had as a child. The bottom part came off (it was meant to be a tracked research APC, I think). The nose would also come off (personnel shuttle?) and it had another ship that piggybacked on top of it. I forget if those were the only four parts, or if there was a fifth. It was really cool and I don't know what ever happened to it... I haven't seen it in more than 30 years, though I'm pretty sure I didn't sell it or throw it in the garbage. It's probably somewhere in the hidden depths of my closet, right next to a Lego that I haven't stepped on yet.I haven't yet gotten into Star Citizen, though I love what I've seen so far (no surprise; it's a Chris Roberts game. I cut my teeth on Wing Commander.) Basically my problem is, I keep getting distracted by the latest OOH, SHINY! Most recently, Metro Exodus.
