I must say, I am intrigued by this project you have. For one, Tagalog is not a mainstream language. Second -- and more importantly, the kids are already fluent. Very interesting. As a Filipino and native Tagalog speaker, I am aware that Tagalog is a deep tongue especially the Old Tagalog used for the Balagtasan Era. In law school, we often used deep Tagalog mostly in pleadings, described as "malalim" or deep. I think I can be of help if you are willing. Ngayon pa lang po, lubos at taos-puso ang aking pasasalamat sa pagkakataong itong minarapat na makasali dito sa marangal at lubhang kapana-panabik na adhikain. Mabuhay po kayo!
