Ota wil brick my phone?? topic

I have moto g (xt 1032) which i have converted to gpe version (first 4.4.4. gpe and than to 5.0.1 gpe) but than I reverted back to 4.4.4. stock rom. Considering that Motorola update to lollipop is approaching , can I update my phone to stock lollipop via OTA or is there possibility to brick my phone?

Thnx ....
