The 1527 and 2260 are two different remote control chips that encode and decode differently. Therefore, the 1527 and 2260 remote controls are not universal. If you want to make them universal, you need to redesign the hardware and software to ensure that the two remote controls can be compatible with each other. So, if you want to use different remote controls, be sure to confirm that they are compatible with each other, otherwise it may cause unnecessary trouble.
If it's a TV remote control. It's the same with TV brands. TV models are the same size. In this case, the remote control can be universal. In addition, if the brand is not consistent, the model is not consistent. Can't be universal.
