Awesome to hear about your growing collection Apg4. All the research I've done says 'no'. to your question.

-1 plant with no offspring will produce, say, 100 fingers of fruit, each fruit maybe 6 inches long.
-1 plant with 5 pups will produce, possibly, a few fewer fingers and the fruit might not be quite as large.

What you sacrifice in fruit size is made up for by higher overall yield between multiple plants from a single corm. Instead of 1 p-stem fruiting, you could potentially have 3 or more flowering at once.

Additionally, having pups already growing in place means you've got replacements rearing to go when it's time to put down the mother stem.

As far as pups vs old stems, old stems will generally win. They're keyed in to the master suite of the corm and will nearly always take priority over a pup. Pups stand an equal chance of eventually fruiting, but rarely over the mother stem. When the mother stem is dead and you have, say, 4 pups of equal age, anything is possible.
