expression “that would have been a monumental moment!”, correct?

[1Stat]

A famous person in the field said to me "I met this popular guy xx in a conference" I wanted to respond by saying "you two gurus met? that would have been a monumental moment"
does this grammatically make sense?
Please advise. Thanks!

First, two things.

Please stop after you ask your question.

If you thank me beforehand it makes me think you're not going to thank me later.

As for your question, perhaps:

That must have been a monumental moment.

(It's probably a good thing you didn't say that.)

Use "would have been" if it didn't actually happen.
