is it possible Make acrylic flame resistant?

Whether or not you could fireproof acrylic, and I doubt very much that you could successfully, a major factor would be whatever chemicals you use, remember that you would be wearing against your skin, at least some part of your skin.
Most of the FR products are not nice to handle and some are in fact dangerous or toxic or sensitising, so I would suggest caution.

I agree 100%.

Until recently, I worked for the largest babygoods retailer in Europe. All the fabric was produced and treated in China. The fire retardant chemicals react with sweat. Different fabrics (often the same fabric but a different shade) absorb more or less of the chemical. So often a shipment would be consigned to the scrapheap because it was fire retardant but would burn the child through touch.

I think it would be near impossible to get the balance right between wearability and an acceptable retardance without ruining the kilt.
