No A browser with its own HTML/CSS parsing, layout, and rendering engine is a large systems project that needs deep expertise in rendering and layout.
What it would actually take: Build an HTML5 tokenizer and tree builder, a CSS parser and cascade, a box layout engine (block, inline, and flex/grid), and a paint layer, in Rust, with a windowing and font stack such as winit and a text shaper. Getting real pages to render correctly is a multi-year effort. It needs experts in browser engine internals, layout algorithms, and text rendering.
