dappled sun when it's very hot and intense - that's good. it CAN take sun if grown completely outdoors in FL.
but since it's a house plant part of the year and you don't want exuberant growth, part shade is best, it'll burn otherwise.
but in such a small pot and good light you'll need to fertilize ev month in summer, even ev 2 weeks with weaker solution. i don't like that thinning of the main trunk - not a good sign!
since you repotted yourself you'll know what the roots are like? or you left center ball undisturbed
?
you should've seen where those off-shoots connect to the trunk and whether they have good roots of their own?
anyways, if you're still considering to separate it, here's a post i found - so it can be done.

i really do hope smbody can comment who's done it a few times...
the main problem with big plant/small pot outside is drying up fast especially in your hot area - and it really suffers when dried up, it needs to be kept moist. you'll need to water it sev times a week, may be ev 2nd day - to run off. you can do one thing to improve the situation: make sure there are big holes in the bottom - position it over a nice bare patch of soil that is not hard (amend it a bit even) - it'll grow roots thru the pot and then it'll be easier to water it. of course, it might grow faster and bigger...and then you'll have to hack the roots off in the fall to take it in. many people bury the pots IN the ground completely and then lift them - much easier to maintain them moist this way. so..just a thought to consider.
i think i've exhausted the well-wishing propositions at this point
please, post when you get some news - am curious how this will go. from time to time people ask what to do with these monsters - the info will come in handy on next round..
