I find your project commendable. Any project that helps people to read the Pali texts directly, is very useful.
Still, I have to say that I do not really believe in trying to read a Pali text without understanding the grammar. In a highly inflected language, like Pali, the grammar elements make up a very important part of the language. One might say that a Pali word consists of two main elements: the vocabulary element (the first part of the word) and the grammar element or the inflection element (the last part of the word). Both elements are equally important. If we drop out the grammar and only go for the vocabulary elements, we can easily miss the sense of the sentence.
Let me illustrate this with an example in English. Here are the bare vocabulary elements of a short sentence:
boy kill snake
Add some grammatical elements, and we get:
The boy killed the snake
The boys are killing the snake
The boy was killed by the snake
The meaning of the sentence may change a little, or it may change radically, by adding different grammatical elements.
A beginner might think that it would be helpful to read Pali texts without worrying with the grammar. But sooner or later a reader has to study the grammar if he or she wants to be able to understand the texts. You would never try to read a foreign language without worrying about the vocabulary. The grammar is equally important.
