In a poker game with a double-sized deck, does a "Flush Pair" have a special rank?

Suppose I play a game of 5-card-draw with a relatively large table (>5 players), necessitating that I double the deck with two standard decks. In addition to adding 5-of-a-kind to the hand rankings (which I believe is ranked above a Royal Flush; please correct me if I'm mistaken) this also adds a few exotic hands to the possible draw. Such as:

• A two-pair flush (♥4, ♥4, ♥2, ♥2, ♥7)
• A one-pair flush (♥9, ♥9, ♥J, ♥8, ♥4)

Do either of these hands hold any kind of special rank in such a game, or are they just ranked the same as a regular Flush? Even if they're ranked the same, do I take the highest card of each hand (the ♥7 and ♥J respectively) or the highest pair of each hand (the ♥4 and ♥9 respectively) when determining their relative rank among each other?

• Never been to this stack before, so it's possible I've tagged the question incorrectly; please let me know what the correct tags should be if I've labeled it wrongly. Apr 15, 2019 at 6:47
• I have never heard of this type of poker, interesting though. I'm sure if you worked out the maths for it you'd find that it'd be a lot hard to make a flush with say ♥4, ♥4 that just 5 random suits, so from a maths pov it should be better than a random flush, and likewise a flush with a double pair again should be higher ranked flush, i.e. ♥9, ♥9, ♥J, ♥4, ♥4. What's the game called?

• @Grinch91 It's just 5-card draw—each player is given 5 cards, they're allowed to, once, replace as many in their hand as they choose, and then what they get after the discard is what they have to the end of the round. Maybe I'm using the wrong name for it? My poker knowledge is highly piecemeal. Anyways, if each player is given 5 cards, and they have the option of redrawing up to 5 cards, then each player could go through 10 cards, meaning a single 52 card deck won't sustain more than 5 players without replacing the deck with the discards—which some dealers don't want to do.
