It might be okay. If that’s all you can get make it work.
Regarding heat, lenses can take up to 50 C, after which point the glue that holds the elements together will cause them to shift. However, I don’t think you should have a problem at one feet. Otherwise humans wouldn’t be able to get that close either! Think about holding a glass of hot water!
Most likely you’ll be shooting at ISO 800. The area looks too small to control halogens, and don’t forget about ambient lighting. White balance will go haywire.. Do you have fire proof diffusion or gels for it? If you don’t have experience operating it, don’t carry it. Carry reflectors, or try to rig a fluorescent box. For the close up shots, you might actually need ND filters.
Simple rule about exposure: expose for the subject. Figure it out on a shot by shot basis. For full texture shoot in the neutral setting. I’m not a fan of the internal sharpening.
Lighting brings out texture. Study the lighting on location. Does the place have windows?
