I think part of this would depend on your experience with hamsters (especially robos). I honestly don't think anyone should get a pair of hamsters until they have a least a couple hamsters worth of experience with the species they want to pair up, especially since robo breeders aren't really a thing in the US so you're not guaranteed you'll get a good pairing (both in terms of genetic temperament and the initial match-up--a breeder would have much more one-on-one time with the hamsters to know who's best with who).
If you feel very confident about robos and reading their body language I'd say go for it, but if you don't quite have that much experience with them yet I'd give it a few years and revisit the idea when you have more knowledge and experience under your belt. 
Generally speaking, I think the general advice on this forum is to discourage pairing, which makes sense. It's very easy to do it wrong if you're inexperienced with hamsters (which, considering the general age demographic of the forum, is most of us) and the benefits, in my opinion, don't outweigh the cons. Don't get me wrong, pairs can and do work out very well and hamsters can form amazing bonds, but there's a lot that has to go right that I don't think is very common in the US considering our lack of ethical breeders (especially for dwarfs).
