Hmmm you're right, i have re readen the rules and as i had only readen them long ago, i did not remembered correctly.
In fact, the reliquary has no physical presence on the battlefield. It's just an upgrade, like a magical object, given to a unit that become "special".
I could keep my first idea and use the wagon as a marker, but it would be a huge marker...
The other option is, as several people did, to make it fitt on a standard base. Then it would just be the last base to remain if the unit takes damages. It would be sufficient to make this unit appear different than others.
So... Keeping the most of my first ideas, I think i will :
- Mold the basement of the wagon with blue stuff and cast it in milliput (to be able to sand and sculpt it).
- Cut the back and suppress the small middle platform, to allow just the two altars to fitt in.
- Keep the two statues.
- Replace the wheels with smaller dwarven or imperial canon wheels in wood.
It would give more or less this at the end (thanks, Paint).

So no horses, no anything. Just peasants pushing fanaticaly on both sides. It may protrude a little bit here and there, but it would not be the first Warmaster unit to do this, eh ?
What do you think, guys ?
