Has anyone come across anything along the following lines?

Let X_1(p)$X_1(p)$ be the compactification of the quotient of upper half plane by Gamma_1(p)$\Gamma_1(p)$ for some unspecified large prime. Let X_1(p)->P^n$X_1(p) \to \mathbb{P}^n$ be some embedding into some projective space. Has anyone explicitly constructed a flat family of dimension one subschemes of P^n$\mathbb{P}^n$ such that generic fiber is isomorphic to X$X$ but a special fiber is something degenerate, yet explicit. For example, has anyone calculated explicitly Grobner basis or some Okounkov-Newton style binomial degeneration?

My interest is primarily in Gamma_1(p)$\Gamma_1(p)$ and embedding by weight one Eisenstein series, but other embeddings and other modular groups (like Gamma(p)$\Gamma(p)$ and Gamma_0(p)$\Gamma_0(p)$) are interesting as well.
