Ninguna de las dos te valdrían. Suena muy mal.
"Formarse una idea" suele ir solo y es como el concepto.
Uno se forma una idea creo que es lo correcto.
Uno forma una idea, seria más correcto Uno tiene una idea.
Depende del concepto, formarse una idea yo lo suelo ver más en formarse una idea equivocada.
Mientras si quieres decir que esta elaborando una idea fabricando una idea es estar pensando una idea. O estoy dandole vueltas a una idea.
Y si es en el momento justo que ocurre la idea, se dice tener una idea.
Me he liado un poco pero espero que te sirva.

Funny Experience
All happened since 6 years when I was studying in Milan with the Erasmus Programme.
I have never seen the snow before that one weekend. My friends and me went to the Alps. I took several lessons to learn skying.
The first day I down the green slope. But always I fell down. One time a few of children asked me if they could taken the chairlift. Obviously I said Yes, Why not?. All trip to the top I was thinkig that I had a big problem. The children haven 9 o 10 and I could fallen down them. At the end when the trip was near I thought the solution. Before to fall down them I slip down, and this is occured.
