The problem with that is, the planting hole will hold water like a bowl drowning the roots. I wouldn't dig more than 6 or 8" inch and re-fill with a well draining soil. If water can't drain though the soil it will be forced to drain to the ground surface. ... Banana roots only grow to about 14" to 16" deep then spread out.
Well my thought is any water which could stand would just go through into this pilot hole during all normal watering,drenching rain would be another story.

Also another drain test could be done into this pilot hole,most land plots have levels of top soil which changes with depth,some get better some not.

This hole would be 6" wide and 20" deep to draw as a safety reservoir,also it would start below the 16" root ball you speak of so in theory most roots beyond the main corm would go laterally and I plan to back fill two feet around the corm with well draining soil.

Peat 50%
Pumice 50%
And some course sand
Ferts and mulch on top
And I will add a custom raised section.

Options are limited because pulling out 18 year old palms is not an option.
