Crafting Suspension Spectra

There is a theorem by Hopkins and Smith which states that for every $n > 0$ there is an ideal $I_n = (v_0^{k_0}, \dots, v_n^{k_n})$ such that there exist a spectrum $X_n$ with the following homology: $$ BP_*(X_n)=BP_*/I_n.$$

I was wondering if it was possible to have a similar but more detailed result.

Is there, for every $n$, an ideal $I_n = (v_0^{k_{0,n}}, \dots, v_n^{k_{n,n}})$ such that:

  1. For every $i$, the limit of the $k_{i,n}$ goes to infinity when $n$ goes to infinity,

  2. There exist a suspension spectrum $X_n$ with $ BP_*(X_n)=\Sigma^{d_n}BP_*/I_n$, for a natural number $d_n$

  3. The $d_n$ don't go to infinity when $n$ goes to infinity.

if it's not possible to satisfy 1,2,3, what about just 1,2? Thanks!!!
