I don't think that extra sense is appropriate here, as it really only applies to a reading that doesn't go with the other senses. I'll propose reviving 2841470, with an xref to here.

koj, daij, etc.

see also the rejected 2841470 for another possible sense to be added.  koj, daij, etc. have a sense for the name of that firework vendor, but that presumably belongs in enamdict

[3][int]
 yell used when viewing fireworks, orig. from names of Edo period fireworks vendors
