Could you build this?
Partial Forking an existing open-source base such as GenOffice makes the app assembly feasible, but a credible office suite spanning docs, sheets, slides, and PDF is a large, complex undertaking. Rendering fidelity and file-format compatibility are hard to get right with vibe coding alone.
What it would actually take: The practical route is forking GenOffice and extending it with Android-native touch UI and performance tuning. The hard parts are the document engines: faithful Office and PDF rendering, spreadsheet formula calculation, and round-tripping file formats such as DOCX and XLSX. That needs experienced mobile and document-engine engineers, with extensive test corpora and long-term maintenance.
