What SAFe? Doesn't Fix

• PMOs still exist
• Gating processes remain unchanged
• Funding processes and budget cycles remain unchanged
• Capex/Opex models remain unchanged
• Release management processes still exist
• Training and go to market processes remain unchanged
• Reporting expectations to senior leaders remains unchanged
• People hiring and on-boarding processes remain unchanged
• Performance management, rewards and renumeration remain unchanged

Sure, you could tackle the above while also implementing SAFe. It's not easy, and jumping aboard an out-of-the-box release train isn't going to get you there. Agile transformation = organization-wide behavioral change.
