D&D 5E Combat question

[Ymdar]

As a high level multiclass barbarian/fighter + rogue (with the dual wielder feat) if I start a combat round with holding two light (finesse) weapons in each hand, can I use the attack action to attack with one finesse weapon, then as part of two weapon fighting attack with the other finesse weapon as a bonus action (possibly scoring a sneak attack), then dropping said weapons, draw a greatsword and use any remaining extra to fight with this weapon?

OR

As a high level multiclass barbarian/fighter + rogue if I start a combat round with holding a greatsword in hand, making a reckless attack then drop the greatsword, draw two light finesse weapons and use any remaining extra attacks with the light finesse weapon and finish the round with a bonus action light finesse weapon attack using the off hand?

I don't see anything to indicate that both cases wouldn't be totally legal. You're fulfilling the use case for dual-wielding, which is making an attack during the Attack action with a light weapon while holding a different light weapon in the other hand.

There's nothing in the rules prohibiting switching weapons during the Attack action.

Both instances rankle my sense of cheesiness, but I think they are technically legal. Note in your second scenario (above), you will need a way to draw two weapons at once (like the Dual Wielder feat).

You are technically allowed to do this, but after the first round you will need to pick up a weapon. You can only pick up one weapon for free.

However, to be honest I wouldn't allow this in my game, it's just too silly and I don't allow goofy edge cases.

I suppose having an enemy scoop up the weapon would be a deterrent.

1) It's technically legal as dropping held items doesn't count as an item interaction, it's no action required thus free, much like when releasing a grappled target. The Devs also have said in the past that The intent is that letting go of something requires no appreciable effort. But picking it up does.

2) Also legal due to Dual Welder letting draw or stow two one-handed weapons when you would normally be able to draw or stow only one.

Many DMs just handwave these sort of item interactions and let characters replace weapons by stowing them rather than dropping them on the ground.

That's a lot of effort for 1d6 extra potential damage per turn, and also something you're going to want to stop doing once you get a magic weapon.

Yeah, it can be a useful tactic in certain situations (if you absolutely need to drop an opponent on this turn, for example), but definitely not something you'd want to do more than once or twice in a fight - switching weapons in the middle of your turn is generally more useful when changing between melee and ranged weapons, say, killing the guy you're in melee with and then tossing a hand axe or dagger at someone else.

Dual Wielder doesn't help here does it? If you stow the swords for free then you can't draw the greatsword for free. You must drop the swords and then draw the greatsword. That means you need to pick up both swords and Dual Wielder doesn't help there.

my favorite way to optimise something similar is to attack, then TWF attack, then stow one weapon and attack again using dueling +2 to damage. Then next turn do it in reverse order (dueling attack, draw weapon, attack, TWF bonus action attack).
