Not sure if I'm really answering your question, but yes, texture { 
pigment { object { text { ... should meet your needs.

I pulled out an old test scene with this :

// ---------------------------------------------------------------------

union {
cone { <0, 0, 0>, Rad, <0, 0, -0.50>, Rad-0.50 }
cylinder { <0, 0, 0>, <0, 0, Len>, Rad }
cone { <0, 0, Len>, Rad, <0, 0, Len+0.50>, Rad-0.50 }

texture {
pigment {
object {
#declare Texte = text {
ttf FontName Str 1, <0, 0, 0>
scale FontScale
rotate -90*y
}
#declare TexteMax = max_extent(Texte);
#declare TexteMin = min_extent(Texte);
#declare Translation = 0.50*<2*Rad, 
TexteMin.y-((TexteMax.y-TexteMin.y)*0.50), Len-TexteMax.z>;
text {
ttf  FontName  Str 1, <0, 0, 0>
scale FontScale
rotate -90*y
translate Translation
} // end of text
pigment { color White*0.25 }
pigment { color Orange*1.15 }
} // end of object
//			turbulence <0.10, 0.20, 0.05>
} // end of pigment


finish { phong 0.90 phong_size 8 }
// normal { cells bump_size 0.15 no_bump_scale scale 0.50 turbulence 0.15 }
} // end of texture
} // end of union


// ---------------------------------------------------------------------


that give the image
