Yeah, you'd be limited to simple usecases. X509 signing or lots of outputs will make the QR code hard to scan. However, if all you want to do is send to a custom script (without using P2SH) I invite you to have a look at
https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/ui/InputParser.java#L86 https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/util/Qr.java#L134 https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/util/Base43.java Basically it's "BITCOIN:-" plus the payment request in Base43 encoded form. I picked Base43, because that's optimized for QR codes.
