Can I realistically reach my glute/toning goals at home with dumbbells up to 15kg?

Options

I’m a 27 y/o woman, 157cm tall, currently 51kg. My main goal is glute growth — aiming for a 7–12cm increase (from ~93cm hips to around 100–105cm), plus overall toning and some upper body definition.

I haven’t trained in years, but I plan to work out consistently 3–4x/week. I already have a diet and workout plan in place.

Currently I have 2kg, 3kg, and 5kg dumbbells, and am about to buy 8kg, 12kg, and 15kg pairs. I also have resistance bands, a yoga mat, and a plastic stool I use instead of a bench.

I know a gym would be ideal, but for now I’d rather stay home. So — if I stick with this setup, would it be enough to help me actually reach my goals over the next 7–12 months? Or am I likely to plateau without going heavier?

If you do think I’ll eventually need more than 15kg, what would I need to add to keep progressing and finally reach my goal? I couldn’t find any good-quality adjustable dumbbells where I live, so that’s not an option unfortunately.

Would really appreciate any insight 🙏🏼
