While height-wise the clones are, in robot mode, legends size, a good comparison would be seaspray
he's very beefy, but sold at the same price point as the other legends. Seaspray is most likely at the absolute top scale of what they can ship as a legend, and the clones are definitely bulkier than him.
Just compare galvatron and broadside for similar issues.
broadside is too small to be a leader, but he's really pushing the bulk of a voyager. Which means he becomes less profitable.
The clones, if sold at the legends price point (10 bucks) would likely make very little profit for the retailers (who have to pay for shipping)
Walmart usually sells toys at a 12-16% markup (higher markups on your 100+ dollar toys)
This isn't a guess, if you work at walmart whenever you scan an item it tells you the markup margin.
More weight translates into a loss of that profit, and that means if the markup drops to 8% to begin with, any sale they had will flat out be selling at a loss.
So doubling them up and selling them at a voyager price point makes sense, since a voyager sells for more than two legends, the profit margin can be more comparable.
