Yeah, I guess it can't be helped if you're unable to secure every member of a combiner team, because some members might be more elusive than others - Heck, it still happens to this very day (looking at you Snarl, Sludge and Rippersnapper)
In the case I described earlier, the rabbit hole gets a bit deeper. The Stunticons I had were the gold-boxed/carded G1 reissues that my father bought for me during a trip to Australia. I lived in South-East Asia at the time, so getting a replacement Wildrider would have been out of the question. Those G1 reissues were Australia/Europe exclusives. The Swindle I used to substitute Wildrider was the G2 version; so you could probably imagine how weird it looked. It's fairly normal nowadays to mix and match teams, and even Wildrider got replaced by Offroad in the official canon. But back when I was a child, having a gestalt character who was 80% G1 Stunticon and 20% G2 Combaticon was kinda weird (til I got used to it).
