You do realize boas are opportunistic feeders so they will always eat when offered unless you are offering them so much that you basically are completely overwhelming their ability to even hold any more food. In the wild boas, eat maybe once every couple months unless they are lucky and in the winter, they go months without food. To add to this, they also must expend energy to find food or wait in ambush which could take months for a meal to wander by and then they gotta pray they dont miss.
In captivity, they do nothing but sit not wasting any calories and just being fed. That's like you sitting in a chair all day and doing nothing but eating. What do you think will happen to you.
And you do realize boas have a much slower metabolism. They poop maybe twice a month if that. Also you do know that boas and pythons organs actually engorge and double in size as well as work harder after a meal for about 10-14 days. This means if you constantly feed your snake food, its' organs are doubled in size and working double time 24/7.
No offense but you really need to do a lot more research before giving advice on feeding for boas. I guarantee if you feed your boa by your standards of feeding, you will be lucky if your boa lives past 10 years.
And here is reading for you about the organs physical changes that they go through after eating.

And to add, if you did this with a BCC, you would have a dead boa in a year if lucky. Too much food for them leads to regurgitation which can become chronic in them which leads to death. They don't handle food nearly as well as a BCI but even your standards will kill a BCI in 10 years if lucky.
