[Callers] Has this dance already been written?

I composed this to have a fairly easy way to introduce diagonal moves to a group that isn't familiar with them. I don’t usually write dances without a N swing, but my attempts to include one haven’t gone well. Suggestions welcome. If it’s original, I’ll call it ChainChainChain Improper A1 N dosido into long lines, Gents face out; Ladies face in. Balance F&B, Box circulate A2 In these longlines (Ladies face out, Gents face in, partner on the right) Balance the wave, Partner Swg B1 on left diagonal, Ladies chain over and back to partner B2 across the set, Ladies chain to N; Star Left
